To all whom 'it may concern:

Be it known that I, J osiAH W. KENNEDY, of St. Louis, in the county ofSt. Louis and State of Missouri, have invented a certain ImprovedHoseGoupling, of which the followin g is a specification:

This invention is an improvement on the subject-matter .of patent No.150,764, granted nie May 12, 1874, for improvement in hosecouplings; andconsists in the formation of the annular sleeve that binds or clamps thehose against the annular rim of the internal tube section with aninwardly-projecting annular flange that engages against an o'set 011 theinternal tubesection, as will hereinafter more fully appear.

The drawing represents my improved coupling, half in elevation and halfin diametric section.

A A are internal tube-sections, each of which have their outer endsscrew-threaded, for the reception of au annular rim, B. The sections A Aare provided with offsets a a, against which the inwardly-projectingflange c of the clamping-sleeve O abuts, so that the sleeve O will beheld in place when the tubesection A is screwed into the rim B, to drawit and the sleeve O together, and thereby clamp the hose between them.In the female part of the coupling the tube-seetion A is provided with asecondary otfset, a1, for the reception of the coupling-sleeve D, whichscrews onto the screw-threaded part a2 of the male part to effect acoupling ofthe parts A A.

The manner of applying the coupling to a hose Will be similar to myformer coupling
